Will the bold text display correctly everywhere?

These are Unicode mathematical characters, not formatting codes. They display as bold glyphs in most modern apps, browsers, and operating systems. A small number of older apps may show them as boxes or question marks.

Do numbers and punctuation get converted too?

Digits 0-9 are converted to their Unicode bold variants. Spaces, punctuation, and non-ASCII characters (such as accented letters) pass through unchanged, since Unicode bold equivalents exist only for the basic Latin alphabet and digits.

Why does this work on social media when markdown does not?

Social platforms strip markdown and HTML. These characters are actual Unicode code points — the platform treats them as regular text, so the bold appearance is preserved without any formatting markup.

Is there any limit on text length?

There is no enforced limit in this tool. However, pasting very long strings into social media fields may be truncated by the platform's own character limits.
